[HTCondor-users] Java universe


First of all, tks for Greg answered my last e-mail, that worked. I am new administrator with HTCondor, and i have another question.

My manager and submit Condor is Ubuntu 20.04 and the execute machines are 18.04. Can this be a problem?

I can't make java universe work, i have installed java in machines. But when i run "condor_status -java ", there is no output. I read in the manual, and i run " /usr/sbin/condor_starter -classad" and there is a error.


root@hpc:~# /usr/sbin/condor_starter -classad
CondorVersion = "$CondorVersion: 8.6.8 Jan 10 2020 BuildID: Debian-8.6.8~dfsg.1-2ubuntu1 Debi
an-8.6.8~dfsg.1-2ubuntu1 $"
IsDaemonCore = True
HasFileTransfer = True
HasPerFileEncryption = True

HasVM = True
HasEncryptExecuteDirectory = True
HasFileTransferPluginMethods = "file,ftp,http,data,https"


I set the variable "JAVA = /usr/lib/jvm/java-11-openjdk-amd64/bin/java" in "/etc/condor/condor_config.local"

In execute machine in file "/var/log/condor/StarterLog", i have the error below:

04/27/21 12:55:49 (pid:20575) JavaDetect: failure status 256 when executing /usr/lib/jvm/java -11-openjdk-amd64/bin/java -classpath /usr/lib/condor:/usr/lib/condor/scimark2lib.jar:. Condo
rJavaInfo old 0

I am sorry if this are basic questions, but i read the manual HTCondor and I didn't find a answer.

Thank you.
